The Challenge

Simultaneously managing the plumbing and structural overhauls of four separate bathrooms on multiple floors without disrupting the structural integrity of the historic floor joists.

Our Solution

We utilized low-profile, high-flow aquatic tracking to reroute internal drainage seamlessly, paired with rigorous acoustic insulation beneath the luxury wood-effect flooring to eliminate internal noise transfer entirely.

The attention to detail and absolute financial transparency provided by Grand Innovations completely redefined our expectations of what a home renovation could be. High standard of work, the extension is beautiful and has added so much value onto our home. Really appreciated the weekly billing, rather than a big amount upfront.
